Anecdotal evidence suggests that stainless steel used with just water has an effect in reducing odors and is so used to reduce odors on hands by chefs. The Water Works® Douching Device is a light-weight (1oz) stainless steel douching device that was developed to aid in the treatment of vaginal odor. Additional anecdotal evidence suggests that douching with the Water Works® Douching Device had little or no affect on the vaginal Eco-System (e.g. good bacteria, Lactobacilli).
